The branch where development work takes place is the master.
Set Up Your Git Environment (for first-time contributors)
Make sure you have your basic Git environment set up.
Choose Something to Work On
Find a bug or feature you like and can manage. If you wish, file it, or go straight to creating a pull request. Make sure your pull request follows the guidelines for pull requests.
Design Your Solution (RFEs & complex bugs only)
If you are developing a feature, or you are working on a bug that involves an interface change, you'll need to go through the design phase:
Develop Your Code and Tests
Bring your local master branch up to date
Update your (forked & locally cloned) repository's master branch with the golden repository's master (IMPORTANT: Your fork's master branch should not be touched with any of your development changes. It should just reflect the golden repository's master, exactly).
git checkout master git pull upstream master |
Update your fork
Push the updated master branch to your fork:
git push origin master |
Create your dev branch
Create a development branch for your bug or feature:
git checkout -b <dev branch> |
Check the development checklist
Look at the checklist for developing code.
Write your code and tests
We recommend developing your code and your tests in parallel.
For large projects, it may help to break down your contribution into smaller, workable pieces. Code for smaller pieces must follow the guidelines for contributions.
PTL Tests
Write an automated test for every change you make, if that test does not already exist. Your PTL tests should provide good coverage of the requirements and your design. Take a look at the steps for testing code.
Put license text in headers for code and tests
If you create new source or test files, make sure that this license text is in the header for all code and test files.
Use the commit-push cycle to perfect your code
- Commit changes in the updated file to your branch with a good commit message. It will be the title of your pull request. Make your commit message relevant and concise, so that it will be helpful to you later:
git add <updated file> git commit -m "<Commit message>" |
Tip: Commit often, perfect later.
- Push the development branch to your fork. By convention, 'origin' points to your forked repository on GitHub:
git push origin <dev branch> |
- Repeat the above steps until you are satisfied with your code change.
Prepare for creating a pull request
- At the point where you create your pull request, your branch should be up to date with master, and your changes should be in a single commit. So:
- Fetch changes made to the golden repository by other contributors. By convention, 'upstream' points to the golden repository on GitHub:
git fetch upstream |
- Squash all your commits into ONE SINGLE COMMIT, and write a meaningful commit message for your commit. You can also use git commit --amend or rebase if you'd rather do it separately. A good commit message is important because it will also be the title of your pull request.
- Finally, push the polished branch to your fork. If you did a git rebase, you'll need to do a force push.
| git push -f origin <dev branch> |
Create a Pull Request
Your code changes are good to go! Go ahead and create a pull request. This allows other contributors to review your changes and provide comments.
Give your pull request a short descriptive title. The title of your pull request (which comes from the title of your commit message) should summarize the bug/issue as it affects a user/customer. If you also have an issue, the titles should match.
In your pull request, add a link to the design document and discussion (for features). If you created an issue, add a link to it.
Add your test logs and other test results to the pull request.
Make sure your pull request follows the guidelines for contributions; if it doesn't, it will not be accepted.
Make your pull request informative. Follow the guidelines in the pull request template.
Don't forget about your pull request after you create it – stale pull requests will be closed without warning.
Get Approval for Your Code and Tests
Your code is ready to be merged into the golden repository when the following are true:
- The code adheres to our coding standards
- You have approval from two people: one maintainer and one other contributor (who can be a maintainer); approvals for code and tests happen on GitHub inside pull requests, not the wiki
Get Changes Reviewed, and Check Them In
Address review comments from other contributors
Address review comments on your code, making changes to your development branch as necessary
- Commit new changes to the same development branch on your local machine
- Push changes to your fork, this will automatically update your pull request on Github
Make reviewing easier
To help reviewers see incremental diffs during the code review process, we recommend that you don't squash again until the code review process is complete
You're done!
Once the maintainers review the pull request, they will merge it in. Congratulations on becoming a contributor to PBS Pro!
Clean Up
Housekeeping: we strongly recommend that you delete the development branch from your forked and cloned repos now.
git checkout master git push origin --delete <dev branch> (deletes <dev branch> from the fork) git branch -D <dev branch> (deletes <dev branch> from local clone) |
Optionally Update Your Issue
